Subject: [PATCH] Spec destroy_all respects paranoid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add a spec to ensure that paranoid models don’t get  deleted by
  destroy_all call.
- ActiveRecords current implementation enumerates over the
  relation and calls &:destroy on each element. If that happens to
change
  sometime in the future this test should notice it.
